Typical perForMance characTerisTics
Characteristic curves are similar for most voltage options of the LTC6655. Curves from the LTC6655-1.25, LTC6655-2.5 and the
LTC6655-5 represent the range of performance across the entire family of references. Characteristic curves for other output voltages
fall between these curves and can be estimated based on their voltage output.
